Mask the read value from the count register in order to return zero correctly
after TC, as per intel datasheet : "If it is not autoinitialised, this
register will have a count of FFFFH after TC"
at the end of gethostanswer()/getanswer()/whatever where it used to
return TRY_AGAIN. This breaks the domain list traversal in ypserv's
async DNS lookup module: it would only retry using the domain(s) from
the 'domain' or 'search' lines in /etc/resolv.conf if __dns_getanswer()
returned TRY_AGAIN.
Changed the test so that either TRY_AGAIN or NO_RECOVERY will work.
This seemed to me the best solution in the event somebody tries to
compile this code on an older system with a different version of BIND.
(You shouldn't do that of course, but then there's a lot of things
in the world that you shouldn't do and people do them anyway.)
comments. Remove reduntant extra addition that was unncessary, and
unneeded mask (asuming inb works correctly).

handlers don't skew the results of isa_dmastatus. The function can be
safely called with interrupts disabled.

Use 'beforedepend' instead of '.depend' to hang automatically-generated
headers off.
XXX the latter is bogus without a 'beforeall' target and explicit ordering
of dependancy generation for targets.
the system is out of memory. The daemon does a minimal amount of work that
increases as the system becomes more likely to run out of memory and page in/out.
The default tuning is fairly low in background CPU usage, and sysctl variables
have been added to enable flexable operation. This is an experimental feature
that will likely be changed and improved over time.
is not sane: if the TTL on a pending but unanswered query hits 0 and the
circular queue entry is removed and free()d, the for() loop may still try
to use the entry pointer (which now points at no longer valid memory).
usually, deleting only the last entry off the end of the queue worked, but
if more than one was deleted, the server would crash. I changed things a
bit so this shouldn't happen anymore.
Also arranged to call the prune routine a bit more often.
for ftp: URLs as well. This can't possibly be done in the general case,
but since we only claim to support http and ftp, we'll adhere to the
bogus requirement (RFC 2068, s. 14.25) anyway... >sigh<

due to the output not being a regular file. Also split the error message
in any error case here to be on two lines to lessen the likelihood of it
being too long to fit on just one.
been extensively tested, but I now can successfully retrieve
<http://www.apache.org/index.html>, so I guess that's a victory of some
sort.
Also move the initialization of ``autherror'' to hopefully eliminate
the reported loop involving authentication. Still need to implement
MD5 digest authentication.
- removed TEST_ALTTIMER.
- removed APIC_PIN0_TIMER.
- removed TIMER_ALL.
mplock.s:
- minor update of try_mplock for new algorithm where a CPU uses try_mplock
instead of get_mplock in the ISRs.
- removed TEST_ALTTIMER.
- removed APIC_PIN0_TIMER.
- removed TIMER_ALL.
apic_vector.s:
- new algorithm where a CPU uses try_mplock instead of get_mplock:
if successful continue as before.
if fail set ipending bit, mask INT (to avoid recursion), cleanup & iret.
This allows the CPU to return to successful work, while the ISR will be run
by the CPU holding the lock as part of the doreti dance.
